Application filed December T 0 all whom it may concern.

Be it known that we, JOSEPH Bow and CHARLES F. l\ Irro1 1nL, citizens of the United States, and residents of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Means for Uniting Two Parts, of which the following is a specification.

The present invention relates to means for uniting two parts and particularly two parts in which one of them has an opening with a cylindrical wall, an object of this invention being to provide a novel means on the other part for fitting it within the opening and engaging with such cylindrical wall in a manner to prevent the accidental separation of the two parts.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter described: the novel features being pointed out in the appended claims.

In the drawings:

Fig. 1 is a sectional view through the two parts united;

Fig. 2 is a plan view of one of the parts;

Fig. 3 is a side view of the same part; and

Fig. 4c is a side view of another embodiment of the invention.

In the illustrated embodiment of the invention, one of the parts indicated at 1 is in the form of a radiator of an automobile and the other part indicated at 2 is in the form of a name plate. The radiator, in this instance, has an opening formed with a surrounding flange 3 bent inwardly to provide an internal cylindrical wall. The name plate has a flange 4 adapted to fit snugly within the opening and to frictionally engage the internal cylindrical wall of the flange 3. In this instance, the annular flange 4: is formed from a cup-shaped'member soldered or Otherwise secured to the rear face of the name plate.

Thefeature of this invention is the provision of a novel means for preventing the Withdrawal of the flange 4 from the opening 3. In this instance, this means is in the form of two oppositely extending spring arms 5 formed preferably from a single piece or strip of sheet steel and secured at 6 at a central point within the flange 1,

the cup-shaped member, in this instance,

having a pressed up boss 7 to which the strip of spring steel is secured. In Order that the pressed up bosswill not collect any great amount of solder beneath the same, the cup-shaped member has radial grooves 8 formed on its under side to permit the flow of solder from the central boss. The spring arms 5 project outwardly beyond the perimeter of the flange 4. and are curved to conform to the perimeter of such flange. In order to permit this projection, the flange 4 may be cut away from its outer edge, as shown at 9 in Fig. 3, at diametrically opposite points or the flange may be merely cut away to provide openings 9*, as shown in Fig. 1, the openings in both forms being suflicient to permit the inward movement of the gripping arms 5.

In uniting the parts, the flange 4 of the part 2 is fitted in the opening of the part 1 and, in being forced in, causes the arms 5 to flex or bend toward the part 2, the latter being moved until it abuts the part 1. The arms 5 tend to prevent the accidental separation of the part 2 from the part 1, due to the fact that any movement of the part 2 away from the part 1 tends to straighten the arms 5 and force them into binding engagement with the cylindrical internal wall of the flange 3, thus locking the part 2 to the part 1.

What we claim as our invention and de sire to secure by Letters Patent is:

1. In combination with two members to be united, one of which is provided with an opening with a cylindrical wall, and the other of which has a cylindrical flange fitted in said opening, spring arms extending through said flange from a point within the latter to cooperate with the cylindrical wall in order to have binding engagement with the latter.

2. In combination with two members to be united, one of which has an opening with a cylindrical wall and the other of which has a cylindrical flange fitting said open-- ing, a strip of spring material secured within said flange and extending in opposite directions through the flange to enter into binding engagement with the cylindrical wall of the opening.

3. The combination with a member having an opening provided with a cylindrical flange about the same, and a second member, of a cup-shaped member secured to said second member and fitting the interior Wall of said flange, and spring arms secured within said cup-shapedmember and extending through the Walls thereof to cooperate with the interior wall of the flange.

4:. The combination with a member having an opening With a cylindrical Wall, of a member having a flange fitting said cylindrical Wall and provided with openings in opposite walls thereof, and a pair of 0ppositely extending spring arms arranged Within said flange and extending through said openings to cooperate with a Wall of the opening. v v

5. The combination with a member having an opening with a cylindrical Wall and a second member, of a cup-shaped member arranged in the second member and having a central boss and also openingsin the sides of said cup shaped member, and aspring strip secured between its ends to the boss and extending through such openings to co operate With the interior Wall of the opening in the first named member.
